Who Is Responsible for a Water Leak Before the Meter?
The water utility usually owns the line up to the meter, so repairs before it are the utility's responsibility, not yours.

What this means for the water that got into your house
The utility fixing the pipe before the meter is a separate question from whether your insurance pays for the damage that water did once it reached your house. If a supply line or connection before the meter burst and water backed up or flooded into your home, that's usually a different coverage problem than a simple pipe repair. A standard policy pays for sudden, accidental water damage, like a pipe that bursts, but not the slow seep of a line that's been failing for months, and it excludes flood water entirely, meaning water that comes from outside and touches the ground before reaching your house. If the water from that outside line counts as flood, only a separate flood policy pays for it. Your declarations page shows whether you carry one, and photographing the damage right away matters either way.
If that water is ruled a flood, a standard policy pays nothing toward the floors, drywall or belongings it ruined, and the gap between that and a real rebuild can run tens of thousands of dollars. Comparing policies now shows which ones offer flood coverage as an add-on and what sewer backup coverage would cost alongside it, before another storm or another slow leak tests what you actually have.
Why sudden pipe bursts and slow leaks get treated so differently
Insurance is built around the idea of something sudden and accidental happening to a house that's otherwise being taken care of. A pipe that bursts overnight fits that. A fitting that's been seeping behind a wall for six months does not, because the policy treats that as a maintenance problem, something a homeowner should have caught. The adjuster who looks at your claim is trying to figure out whether this was a one-time accident or a condition that built up over time. That answer decides whether the claim gets paid.
What they look for is physical evidence of how long the water was moving. Stains with layers, wood that's swollen and dried more than once, mold that's established and spread, drywall that's soft in a wide area rather than a single wet patch, these all point to a leak that had been running for a while. An insurer will call that a maintenance failure rather than a covered loss. A clean break in a pipe with water that clearly just started pooling points the other way. This is why finding a slow leak early and calling it in right away matters more than almost anything else. The gap between a leak that started last week and one that started last winter is often the gap between a paid claim and a denied one.
Sewer and drain backups sit outside this sudden-versus-gradual question entirely. A standard policy typically excludes backup damage unless you've added a sewer and drain backup endorsement, regardless of whether the backup was sudden. Water that backs up through a floor drain or a toilet during a heavy rain is common enough that most insurers sell this coverage separately, usually for a modest added premium with its own lower coverage limit, often far below the dwelling limit itself. If a line before the meter failed and pushed water back into the house through the drains rather than flooding in from outside, this endorsement, not your base policy, is what pays.
Mold brings its own limit even when the water that caused it was covered. Most policies cap mold remediation at a set dollar amount, sometimes a few thousand dollars, regardless of how much the rest of the water damage claim pays out. If mold took hold because a covered leak sat unaddressed for several days before anyone noticed, the mold cleanup itself may still hit that lower cap. Checking what that number is before anything happens, and drying out any wet area within the first day or two when you can, keeps a small claim from turning into a dispute over a sub-limit nobody read until it mattered.
What to do in the first hours after you find water
Shutting off the water is the first move, at the main valve if you can't find the source fast enough. Every minute water keeps moving is a minute that can turn a sudden, covered loss into something that looks gradual by the time anyone inspects it. If a water heater or appliance is the source, shutting off its own supply valve may be enough and saves you from killing water to the whole house.
Photograph everything before you move or dry anything, the standing water, the source if you can see it, the stained walls or ceiling, the swollen floor. Take wide shots and close-ups. Write down the date and time you found it, even in a phone note, because insurers ask when the damage was discovered and that timeline matters more than people expect. If you can show you called it in within a day of finding it, that works in your favor regardless of how the leak itself gets classified.
Call the claim in before you start cleanup, not after. Starting repairs first, even reasonable ones like running fans or pulling up carpet, can look like you're destroying evidence of how bad it was, and some insurers want to send an adjuster before major changes happen. Drying out the area is still the right call once the claim is open. Letting water sit for the sake of a better photo risks mold taking hold, which brings its own low payout cap regardless of what the water damage itself pays.
Keep receipts for anything spent on emergency mitigation, a wet vac rental, a plumber's emergency call, fans run from a hardware store. Most policies reimburse reasonable costs to prevent further damage even before the claim is fully evaluated, and having those receipts ready means that part of the process doesn't stall waiting on paperwork you didn't think to save.
Before you go
Pull up your declarations page. Check whether you carry a flood policy and whether a sewer and drain backup endorsement is listed. If neither is there, see what adding them would cost.
